How many Heartline coasters exist?

I was in Nagashima Spaland 2 weeks ago, and rode a heartline coaster (my first). How many of these coasters exist, and where? Any in the states?

Ultra Twister at SFAW.

The heartline at SFGadv I think is closed as of now.

Interesting.........The coaster in Nagashima was also called the Ultra Twister. I guess it is safe to assume that they are all clones? I wonder which one came first?

Look at all the coasters called Ultra Twister. They all look like heartline coasters to me.

There are some more heartlines in Japan, where TOGO is based...

Viper at Six Flags Great Adventure is a heartline coaster with actual drops and turns. It is an OK ride, but it closed all season, and is expected to be taken down do to negative feedback on the ride.
